Effect of Projectile Incident Angle on Penetration of Steel Plates

Abstract

High speed impacts are complex phenomena influenced by various parameters. To predict the structural damage caused by a high speed impact, it is necessary to investigate the effect of various impact conditions, such as the incident angle, the nose shape and diameter of the projectile, and the material and thickness of the plate, on the behavior of the structures. Although the projectile incident angle considerably influences the behavior of steel structures, studies on this subject have been limited. Thus, this study investigates the effect of the projectile incident angle on the deformation of the steel plate and the penetration behavior of the projectile. It was found that the projectile incident angle significantly influences the plate deformation and the angle, velocity, and kinetic energy of the projectile.
